I suspect that the best workaround for this would be, upon the first time a port is opened, * set the timeout for the setup URB to 0.5sec or so. * remember that it timed out and don't attempt to do it again. * don't block the open until there's a response Given that Huawei likes to recycle their USB product IDs, I don't see much chance to proactively prevent this from happening entirely. -- -- Matthias Urlichs
